A computer-implemented method and data processing system for modelling and/or simulating and/or emulating a battery

The present patent application relates to a method for simulation of insertion batteries based on equivalent circuit models that are derived in such a way that they preserve consistency to physiochemical processes in real batteries thereby ensuring their consistency with electrochemical models. Due to its consistency to physiochemical processes in real batteries, elements of the equivalent circuit model, which virtually represents a battery, replicate specific processes in batteries, and due to its consistency with electrochemical models, element of such an equivalent circuit can be analytically derived from parameters that are related to material and topological as well as geometrical characteristics of the battery cells. Due to its consistency with physiochemical processes in real batteries and its applicability to DC and AC current stimuli, the proposed method is applicable for advanced functionalities of the Battery Management Systems (BMS).

Reaction and transport mechanisms in lithium-sulfur batteries

Miran Gaberšček, a member of this project group, was a plenary speaker at the international symposium on electrochemistry held in Split, Croatia. In the first part of lecture he presented an overview of achievements on various battery systems including on modelling of LiFePO4. In the second part the emphasis was on the impedance modelling of Li-sulphur batteries.

Functioning of insertion battery electrodes: understanding the correlation between local phenomena and macroscopic output of battery cell

In the literature, there were identified many transport-reaction phenomena that take place locally during charging and discharging of the batteries. In the lecture, we attempted to bring the knowledge together to explain results of the macroscopic electrochemical measurements. We did not rely only on typical standard electrochemical measurements, but we performed numerous sets of new tailored measurements that revealed several interesting phenomena: non-linear dependency of the voltage to the current, memory effect, increase of rate of reaction by using surface films, changing the angle of the Warburg impedance response portion during the charging and discharging of the battery.
